Based on ₹40,000 Basic Pay at 60% DA
How Bihar DA is Calculated
Dearness Allowance is generally calculated by applying the applicable DA percentage to eligible Basic Pay.
Example Basic Pay: ₹40,000
Example DA Rate: 60%
Monthly DA: ₹24,000
Basic Pay + DA: ₹64,000
Use Eligible Basic Pay
Do not enter gross salary. DA calculation normally starts from the eligible Basic Pay amount.
Use Applicable Period
DA rates change through Government orders, so choose the rate applicable to the month or period you are calculating.
DA is Only One Component
HRA, transport allowance, medical allowance and other eligible salary components are separate from this DA calculation.
Do Not Automatically Use Central Government DA
Bihar Government employees should use the DA rate approved by the Bihar Government for their applicable pay structure and period.
A Central Government DA announcement should not automatically be treated as applicable to Bihar State Government employees.
Check Bihar Finance Department Orders
Always verify the DA rate, effective date and eligibility from the applicable Bihar Finance Department notification.
